well, it is .... 270 degrees....so cosine of 0 is 1, cosine 90 is 0, cosine 180 is -1, cosine 270 is o, so sec = 1/cosine= undetermined...

At 3π/2, a rotating arm ends up on the negative y-axis (270°)

If we consider a unit circle, then the terminal arm ends up at (0,-1), that is,

x=0, y = -1, r = 1

cos (3π/2) = 0/1 = 0

so sec(3π/2) = 1/cos(3π/2) = 1/0

which would be undefined.
